Finafloxacin is an orally active fourth-generation fluoroquinolone broad-spectrum antibiotic. Finafloxacin exhibits stronger antibacterial activity in acidic pH environments and is not easily affected by bacterial multidrug efflux transporters. Finafloxacin is effective against a variety of extracellular pathogenic bacteria, and can also accumulate in macrophages, showing excellent antibacterial activity against intracellular Staphylococcus aureus, Listeria monocytogenes, Legionella pneumophila, Burkholderia pseudomallei, and other pathogens. Finafloxacin has been approved by the U.S. FDA for research on acute otitis externa mediated by Pseudomonas aeruginosa. Finafloxacin is also used in studies related to diseases such as melioidosis, inhalational tularemia, and inhalational plague .

Exosomes Liposome

GALA is a pH-responsive amphipathic peptide consisting of 30 amino acids, which acts as a lung endothelium-targeting ligand. GALA undergoes a conformational transition from random coil to α-helix in an acidic environment at pH 5.0, thereby inducing endosomal membrane destabilization and fusion. GALA-modified liposomes traverse lung endothelial cells via clathrin-dependent endocytosis and transcytosis, and specifically accumulate in the lungs after intravenous injection. GALA significantly promotes the cytosolic release of cargos carried by exosomes, plasmids and liposomes, effectively enhances gene transfection efficiency, and drives gene knockdown of functional macromolecules (such as siRNA) in alveolar epithelial cells (with no significant cytotoxicity at effective concentrations). GALA serves as a critical tool for studies on lung cancer metastasis (e.g., melanoma lung metastasis) and lung-targeted drug delivery systems .

OF-02 is an ionizable lipid for mRNA delivery and a key component of lipid nanoparticles (LNPs). OF-02 is protonated in the acidic endosomal environment to promote endosomal escape of mRNA and efficiently induce protein expression in target cells. OF-02 relies on the pH-responsive membrane fusion properties to form a complex with mRNA and destroy the endosomal membrane structure to achieve mRNA release in the cytoplasm. OF-02 is mainly used in the development of mRNA vaccines, gene editing, and protein replacement therapy[1][2][3].

RALA peptide is a cationic amphiphilic delivery agent targeting cell membranes, which forms nanoparticles through electrostatic interactions with anionic drugs. RALA peptide has pH-responsive binding properties, which can enhance the α-helical conformation in an acidic environment and destroy the endosomal membrane, promote the release of drugs into the cytoplasm, and exert efficient intracellular delivery activity. RALA peptide can be used in cancer research (enhancing the activity of bisphosphonates against prostate cancer and breast cancer cells) and bone tissue engineering (promoting osteoblast collagen deposition and extracellular matrix mineralization) .

Synonyms: Thymolsulphonephthalein
Thymol blue is a reversible pH indicator that responds to the pH of the solution through structural changes of protonation and deprotonation. Thymol blue is red (HI - form) under acidic conditions and blue (I 2- form) under alkaline conditions. Quantitative detection is achieved through the absorption peak shift (435 nm/596 nm) of the UV-visible spectrum. Thymol blue selectively responds to pH changes, changing from red to yellow at pH 1.2-2.8 and from yellow to blue at pH 8.0-9.6. Thymol blue can be fixed in a silica gel matrix through sol-gel technology to form a solid-state sensor for in-situ pH measurement in the marine environment and acid-base monitoring in the biomedical field[1][2].

NPE-caged-proton is a reagent that releases protons under UV light and has the activity of activating the fusion protein GP64 under weak acidic conditions. NPE-caged-proton can promote the binding of enveloped viruses to liposome membranes with acidic phospholipids in an environment of pH 4.0 to 5.5, thereby initiating membrane fusion. The ultraviolet unblocking effect of NPE-caged-proton can lower the environmental pH, thereby triggering the process of viral membrane fusion. When studying the interaction between viruses and cell membranes, NPE-caged-proton provides a valuable tool for revealing the subtle behaviors of viruses in different chemical and biochemical environments .
